It is used by mixing more than one species.

[0010] The amount of the thickener added is 100% of the above main raw material.
It is preferably 4 to 10 parts by weight. The water retention agents used in the fishing bait or aquaculture fish feed of the present invention include gum tragacanth, gum arabic, sodium alginate, casein, sodium chondroitin sulfate, dextrin, sodium hexametaphosphate, funori, soybean casein, lecithin, konjac powder, and gelatin. Gum arabic, sodium alginate, dextrin, casein, and gelatin are particularly preferred, and these water retention agents may be used alone or in combination of two or more.

[0011] The amount of the water retaining agent added is 100% of the above main raw material.
It is preferably 1 to 5 parts by weight. Binders used in the fishing bait or cultured fish feed of the present invention include potassium polyphosphate, sodium polyphosphate, glyoxal, borax, boric acid, sodium metaphosphate, potassium metaphosphate, propylene glycol alginate, and polyacrylic acid. Examples include sodium, carboxymethyl cellulose calcium, triethylene glycol, glycerin, dipropylene glycol, and methylolated melamine. Particularly preferred are potassium polyphosphate and glycerin.
It is used by mixing more than one species.

[0012] The amount of the binder added is 100% of the above main raw material.
It is preferably 0.2 to 1 part by weight. Furthermore, the fishing bait or cultured fish feed of the present invention may contain a fish-attracting substance, a preservative (preservative), and the like, if necessary. Examples of the fish attractant include fish oil, garlic, etc., and preservatives include erythorbic acid, calcium disodium ethylenediaminetetraacetate, guaiac butter, butylated hydroxytoluene, butylated hydroxyanisole, and the like.

[0013] The amount of the fish attractant added is based on the main raw material 1.
The amount of the preservative added is preferably 0.001 to 0.05 parts by weight per 100 parts by weight of the main raw material. . Furthermore, the fishing bait or cultured fish feed of the present invention may contain additives other than those mentioned above, such as a gelling agent, within a range that does not go against the spirit of the present invention.

Next, a preferred embodiment of the production of the fishing bait or cultured fish feed of the present invention will be explained. First, the above-mentioned thickener and the above-mentioned water retention agent are added to the above-mentioned main raw material in the above-mentioned ratio, and the mixture is stirred and mixed while heating. Heating is at a temperature of 60 to 90°C,
Do this for 30-60 minutes. If the temperature is lower than 60°C, the thickener and water retaining agent will not dissolve well, and if it is higher than 90°C, the main raw material will undergo thermal denaturation, change its color, and lose its luster. In addition, if the heating and mixing time is less than 30 minutes,
The above-mentioned thickener and water retention agent do not mix well with the main raw material.

[0015] After mixing the above-mentioned thickener and the above-mentioned water retention agent with the above-mentioned main raw materials, a binder is added and the mixture is stirred and mixed for 5 to 10 minutes. After adding the binder, it is sufficient to stir and mix using only residual heat. The reason why the binder is added later is that if the thickener and water retaining agent are added after the binder is added, the main raw material and the thickener and water retaining agent will not mix well.

Furthermore, if a preservative or the like is to be added, it may be added after the binder has been mixed, and the mixture may be mixed for about 5 to 10 minutes. After mixing, the mixture is cooled to room temperature to obtain the fishing bait or cultured fish feed of the present invention. The viscosity of the fishing bait or cultured fish feed of the present invention can be adjusted by increasing or decreasing the amounts of the thickener, water retention agent, and binder.

The present invention will now be explained in more detail with reference to Examples.
